To all whom it may concern: q

Be it known that l, Gnonen H. iDANDS,

a. citizen of the United States, residing at Los .ingeles, in the county of LosAngeles and State of California, have invented new and useful improvements in Grease Cups, of which the following is a specification.

This invention relates to new and useful improvements in what is commonly termed grease cups, the diiierence being, however, that in my invention I employ a fiuidoil rather than a solid oil. l

The principal object of this invention is to provide a device which will act as a reservoir for retaining a quantity or lubricant which device will automatically dispense a. small amount of the lubricant to the bearing to which it is attached through the acceleration of the vehicle upon which the sam is secured.

Another object is to provide a device of this character which is simple in construction, cheap to manufacture, and one which may not become deranged.

A. still. further object is to provide a device which. will not dispense oil when the vehicle upon which the same is attached is at rest, or while the vehicle is upon an incline.

Other objects and advantages will be ap parent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which l ke numerals are employed to designate like parts throughout the same, i

Figure l is a vertical crossn section on the line ll-'l of Figure 2,

Figure 2 is a l'iorizontal cross sectlion taken on the line 2-2 of Figure 1, and

l igure 3 is an enlarged detail fraginentary view taken on the line 3-3 of Figure 1.

In the present day oil cups considerable difficulty has been experienced in securing the correct flow of lubricant to the bearing due to the resistance offered by the lubricant to the feeding mechanism, this applies more especially to the heavier grade of oils, which conditions I have sought to overcome by eniploying an internal weighted reservoir having a port therebeneath which port is closed by a Hatvalve face. By this construction I allow the oil to pass beneath the valve when the receptacle is tipped, owing to the affect of inertion in starting or stopping of the car and after this oil has been released from the receptacle it is free to new to the bearing without being impeded by any further valves.

In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates a threaded plug adapted to be screwed into the bearing to he lubricated. This plug is centrally bored as shown at 6 and is provided with lateral bores 7 and 8. The upper surface of this plug is flat so as to provide a seat 9, the purpose of which will be later seen.

Shrunk or otherwise secured to the plug 5, as shown at ll, is a housing 12. This housing extends upwardly and'is provided with a fluted edge 13, within which is positioned a ring 14. This ring 1% is provide fl with inturned ends as shown at 16 and 17, which are, adapted to engage the annular recess 18 formed in the plug 19, which is in turn secured to a cover 21. i

A handle :22 is secured to the plug 19 for the purpose of providing a grip for removing the cover 21 from the housing 12. Mounted within the housing 12 is a reservoir 23. This reservoir is made with relatively thick walls so as to give the same a substantial weight.

A boss 24; is formed upon one end of this receptacle and has a port'26 extending therethrough. The outer face of this boss is provided with a Hat surface, which fiat surface is adapted to contact the flat surface of the seat 9 of the plug 5.

A cover 27 is pressed upon the receptacle 23 and is provided with an enlarged opening 28, which opening serves the purpose of acting as a filling means and at the same time provides for the accommodation of the lower extremity of the plug 19.

The operation or" my device is as follows Assuming that the parts are in the position shownin Figure 1 and that the reservoir 23 has been filled with a lubricant represented by the letter A and that the device has been attached to the bearing of an automobile, we will assume that the car has been started with the result that the acceleration will act upon the reservoir 23 and cause the same to tilt, due to the fact that it is slightly topheavy. This will allow during the period of tilting, a small amount of lubricant to pass through the LIL) port 26 and on to the flat face 9 of the plug 5. This oil will run off from this face, pass through the ports 7 and 8 and through the bore 6 and to the bearing to be lubricated. Should the vehicle be brought to rest upon a grade, the receptacle as a whole, will slide sideways so that the side of the receptacle will rest against the side of the housing. This condition allows the port 26 to remain closed thus preventing a wastage of oil.

It is of-courseunderstood that the receptacle will move from side to side as the vehicle proceeds, and it is due to the inequalities of the road which causes the receptacle to move away from the sides of the housing and to maintain a substantially central position.

It is to be understood that the'form of my invention, herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims Having thus described my invention, I claim 1. In a device of the character described, the combination with an oil cup adapted to be secured to a bearing, a fiat surface formed within said oil cup, a receptacle mounted within said oil cup and being provided with a flat bottom surface for operating with the flat surface first mentioned, a boss formed on said receptacle and means for discharging a lubricant from said receptacle to said flat surfaces.

2. In a device of the character described, an oil cup comprising a threaded discharge plug adapted to be secured to a bearing, a housing secured to said plug, said discharge plug having a. fiat upper surface, a receptacle having a fiat bottom surface adapted to be positioned on said plug. and to have intimate contact therewith, and means for communicating between said vertical bore and the interior of said housing, a flat surface formed on the upper extremity of said plug, a receptacle mounted within said housing, said receptacle having considerable weight, a boss formed upon the lower extremity of said receptacle, said boss having a flat surface adapted to contact the flat surface of said plug, and a port extended through said boss and communicating with the interior of said receptacle for discharging the oil upon flat surfaces in a manner whereby it will be conveyed to the bearing through the medium of the bore of the plug, the contact between said flat surface acting as avalve for the purpose of preventing a discharge of lubricant during the contacting period of said flat surfaces.

4. In a device of the character described, a plug adapted to be secured to a. bearing, a cylindrical housing secured to said plug, said housing having vertical walls, a vertical bore within said plug, lateral bores coin municating between said vertical bore and the interior of said housing, a flat surface formed upon the upper extremity of said plug, a receptacle mounted within said housing, said receptacle having vertical walls throughout the major portion of its length and being relatively heavy, a boss formed upon the lower extremity of said receptacle. said boss having a fiat surface adapted to contact the flat surface of said plug and a port extended through said boss and coinmunicating with the interior of said receptacle, said port being sealed by said flat surface of said plug when said flat surface of said boss contacts the same.
